PETER JEPBEN, 0F WORCESTER, IASSACHUQETTS, ASBIGNOB TO THE EB-ICU STEEL AND WIBECOMPANY OF NEW JERSEY, A OORPOBATION OF NEW JERSEY- APPARATUS FOR ELEGI'BOGLLVANIZING.

Application filed February 8, 1827. Serial 1T0. 168,922.

This invention relates to apparatus for electro-galvanizing, and while not limited thereto, relates more particularly to apparatus for electro-galvanizing wire and similar articles of manufacture.

Heretofore it has generall been the Jractice to mount the anodes an Ipig zinc in the bottom of the deposition tan s and to pass the articles to be galvanized through the solution above the anodes and zinc, and to constantly turn the articles so as to provide an even coating on all sides of the articles.

When coating wire invthe tanks as heretofore constructed it was necessary to twist or turn the wire while it was being moved through the electro-galvanizing tank so as to evenly coat the wire, thus slowing up the operation and at best providing a more or less uneven coating of zinc. I

The present invention provides two sets of anodes andpig zinc, one above the other, so that the articles to be coated may be passed between the bodies of zinc and ave an even coating deposited thereon w1thout turning the articles.

In the drawings- A Figure 1 is a plan view of part of an electro-galvanizing tank embodying my invention, the vertical separator support being omitted for clearness.

Figure 2 is a longitudinal sectional elevation on the line II-II of Figure 1.

Figure 3 is a transverse sectional elevation taken on the line III-III of Figure 2.

Figure 4 is an enlarged detail view of one of the upper anode members 5 partly in section to show the lead covering.

Referring more particularly to the drawings, the numeral 2 desi nates the tank body as a whole, which is 0 standard vconstruction.

A pair of copper bus bars 3 and 4 are mounted along the one side of the tank .body.

A plurality of angle ,iron zinc holders or anodes 5 are sup orted across the tank in spaced relation with the bottom of the tank. The angle iron holders 5 are covered with sheet or strip lead 6 and form anodes which are adapted to support the-pigs of zinc 7, and are connected to the bus bar 3 by copper connectors 8 which are connected to the lead sides 9 of the holders 5.

plurality of anodes 10, composed of A strip ead, are mounted on wood supporting bases 10 mounted on the wooden spacing strips 11 on the bottom of the tank 2, and

are provided with side portions 12 which underlie the side portions 9 of the holders w provide for the energizing 5 so as to form an electrical connection therewith, and of the anodes 10 from the bus bar 3. The

A plurality of cathodes 16 are mounted in the tank 2 and are connected by side members 16 and connectors 17 to the bus bar 4 anodes 10 supporta plurality of pigs of zinc I A i of opposite polarity from the bus bar 3 so it A wooden support 19 is secured *to the I spacing strips 11 to prevent the wire sa n and touching the anodes 10, thus iorm ii g g short circui An upper transversel arranged separator support 18 is rovide to support vertical separator mem rs 20 which serve to maintaln the wlres or other articles beingv coated in transversely spaced relation.

The tank 2 is adapted to be filled with an acid or electrolytic solution of standard composition, and the bus bars 3 and 4 are adapted to be connected to a generator or generators or other source of tric current supply. 7

In operation, the anodes will be energized with thepositive current, and the wire or other articles to be electro-plated or electropositive elec-' galvanized will be energized with them ti've current by contact with the catho and passed through thesolution in the tank series of anodes, a bus bar extending parallel with said tank, means connecting all of said anodes with said bus bar, a second bus bar extending parallel with said tank, a plurality of stationary cathodes mounted in said tank at an elevation intermediate said anodes and adapted to be engaged by the wire or other material being passed between said series of anodes to be plated, means connecting said cathodes wit-h said second named bus bar, wood strips fixedly mounted below said second series of anodes and at least one wood moauze supporting memberfixedly mounted above the upper faces of said second series of anodes to prevent the wire being plated coming into contact'with said anodes, and vertically arranged non-conducting separator bars for maintaining a plurality of wires in spaced relation When they are being simultaneously passed through said tank.

In witness whereof, I have hereunto signed my name.

PETER JEPSEN. I
